Protecting your power network and enabling
high value communication services

Originally valued primarily for its potential to help eliminate power outages and assure quality and reliability of electric power supply, teleprotection is now increasingly perceived as a growth engine for power utility businesses.

TTC MARCONI solutions are secure, efficient, scalable and accessible to allow power utility companies supply affordable clean energy while swiftly responding to arising opportunities in communications, Smart Grid and Internet of Things.

Basic functions

  • Prevents losses caused by power line failure (short circuit, cut)
  • Avoids unnecessary shutdowns of related power lines
  • Provides fast and reliable command transmission for power line protection (tripping, permission and blocking). Transmission of commands with minimum possible delays (less than 2ms)
  • Together with relay protection, isolates the troubled or damaged part of the power grid from the rest of the network
  • Highly secure transmission-resistance to unwanted commands with probability of error lower than 10-28
  • Allows transmission of commands and data via various transport networks such as TDM (SDH, PDH, RR, Data), IP based, and optical fiber

Supports variety of teleprotection devices

  • CMD/BIN
  • 2w/4w analogue 50/60Hz protective devices
  • Digital protective devices (C37.94, proprietary)

Transmits variety of voice and data protocols

  • Legacy data
  • 2w/4w E&M
  • FXO/FXS (Magneto - LB, CB, hotline)
  • Ethernet (p-p, p-mp)
  • E1

Advanced functions

  • Can transmit both analogue and IP based communication for hybrid network implementations, including teleprotection commands, Voice and Data over TDM, and optical and IP lines
  • Supports both digital protective relays and legacy analogue relays (50/60Hz)
  • Supports mixed environments where both digital and analogue protective relays can be used in one power grid
  • Support for a Phase Synchronization function to smoothly connect power sources (Power Plant) to the power grid
  • Original solutions supporting migration from TDM to IP based networks where both types of devices and networks co-exist side by side
  • Ability to transport legacy RTU (Remote Terminal Unit) communication over TDM, optical and IP based networks
  • Variability of services in terminal node points. Hybrid design for both Fast Ethernet and serial interfaces

About us

TTC MARCONI s.r.o has been providing its customers with modern telecommunications solutions for over twenty years, continuing the nearly sixty years’ tradition of specialist knowledge of the Telecommunications Research Institute, whose experts were involved in the creation of the company.

During the past twenty years we have successfully expanded to the demanding foreign markets of the Russian Federation, Ukraine and Slovakia, where we have built our own subsidiaries. Thanks to our experience in power distribution networks, we know how to realise communication networks on high-voltage lines and how to protect these lines. We also implement the latest packet systems in technological networks.

Our success strarted with a range of our own products, deployed en masse in telecommunications networks. From these we have, over time, developed specialised systems optimised for safe application in critical infrastructures. Our unique know-how, gained over time, is further utilised in high-end system integration projects, chiefly in the energy and transport sectors. This is possible thanks to the successful cooperation of our specialists with renowned global businesses active on the current telecommunications market.

In the field of railway telecommunications, we implement our own technical solution, providing interfaces between traditional railway and modern communications technologies.
